Palatini Variation in Generalized Geometry and String Effective Actions
Branislav Jurco, Filip Moucka, Jan Vysoky
We develop the Palatini formalism within the framework of generalized Riemannian geometry of Courant algebroids. In this context, the Palatini variation of a generalized Einstein-H…
Effective Actions for -Models of Poisson-Lie Type
Branislav Jurco, Jan Vysoky
(Quasi-)Poisson-Lie T-duality of string effective actions is described in the framework of generalized geometry of Courant algebroids. The approach is based on a generalization of…
Poisson-Lie T-duality of String Effective Actions: A New Approach to the Dilaton Puzzle
Branislav Jurco, Jan Vysoky
For a particular class of backgrounds, equations of motion for string sigma models targeted in mutually dual Poisson-Lie groups are equivalent. This phenomenon is called the Poisso…
Kaluza-Klein Reduction of Low-Energy Effective Actions: Geometrical Approach
Jan Vysoky
Equations of motion of low-energy string effective actions can be conveniently described in terms of generalized geometry and Levi-Civita connections on Courant algebroids. This ap…
Generalized geometry and non-symmetric gravity
Branislav Jurco, Fech Scen Khoo, Peter Schupp +1
Generalized geometry provides the framework for a systematic approach to non-symmetric metric gravity theory and naturally leads to an Einstein-Kalb-Ramond gravity theory with tota…
Heterotic Reduction of Courant Algebroid Connections and Einstein-Hilbert Actions
Branislav Jurco, Jan Vysoky
We discuss Levi-Civita connections on Courant algebroids. We define an appropriate generalization of the curvature tensor and compute the corresponding scalar curvatures in the exa…
Leibniz algebroids, generalized Bismut connections and Einstein-Hilbert actions
Branislav Jurco, Jan Vysoky
Connection, torsion and curvature are introduced for general (local) Leibniz algebroids. Generalized Bismut connection on is an example leading to a sca…
Extended generalized geometry and a DBI-type effective action for branes ending on branes
Branislav Jurco, Peter Schupp, Jan Vysoky
Starting from the usual bosonic membrane action, we develop the geometry suitable for the description of -brane backgrounds. Using the tools of generalized geometry we derive th…
Nambu-Poisson Gauge Theory
Branislav Jurco, Peter Schupp, Jan Vysoky
We generalize noncommutative gauge theory using Nambu-Poisson structures to obtain a new type of gauge theory with higher brackets and gauge fields. The approach is based on covari…
On the Generalized Geometry Origin of Noncommutative Gauge Theory
Branislav Jurco, Peter Schupp, Jan Vysoky
We discuss noncommutative gauge theory from the generalized geometry point of view. We argue that the equivalence between the commutative and semiclassically noncommutative DBI act…
p-Brane Actions and Higher Roytenberg Brackets
Branislav Jurco, Peter Schupp, Jan Vysoky
Motivated by the quest to understand the analog of non-geometric flux compactification in the context of M-theory, we study higher dimensional analogs of generalized Poisson sigma…
